GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 422,414, dated March 4, 1890.

Application filed February 28, 1889. Serial No. 301,547. (No model.)

To all whom it may concern:

Be it known that I, WVATSON M. HOLMES, a citizen of the United States, residing at H00 sick Falls, county of Rensselaer, and State of New York, have invented certain new and useful Improvements in Grain Binders, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates more particularly to the mechanism by which the action of the packers is arrested and the binder started when a certain predetermined amount of straw has accumulated in the binder-receptacle, and by which the binder is stopped and the packers again started when the gavel has been bound.

My invention consists in the combination, with a constantlyrevolving driver provided 011 either side with clutching mechanism and mounted loosely on its shaft, of a clutch fast on the shaft on one side of the driver and a spring-actuated clutch loose on the shaft, with means for causing, through the accumulation of grain in the binder-receptacle, the driver to engage one clutch to start the binder and to be disengaged by the starting of the binder from the other clutch, which operates the packers.

My invention furthermore consists in certain other details of arrangement and combinations of parts, as will be more fully hereinafter described, and pointed out in the claims.

Referring to the accompanying drawings, in which similar letters of reference indicate like parts, Figure 1 is a top plan View of a machine embodying my invention. Fig. 2 is a side elevation showing the packers, the tripping and actuating devices, and the needlearm shaft. Fig. 3 is a perspective View showin g the lever for sliding the packer-shaft to disengage the clutch secured thereto from the driver, and to consequently stop the packers. Fig. 4. is a side elevation of the clutches and the driver, also showing-part of the tripping device. Fig. 5 is a vertical section through the driving-gear on the binder-shaft. Fig. 6

is a perspective view of the driving-pinion of the binder and of the shipping device for arresting the action of the packers.

9, and 10 are views of details of the tripping :devices. Fig. 11 is a perspective view of the yoke which forms part of the tripping mechanism. Fig. 12 is a perspective view of the tripping-lever and its connections with the yoke shown in Fig. 11.

A is the binder-frame, of the usual form of construction. In the upper limb, which is formed hollow, the packer-shaft A has its bearings. Outwardly-extending offsets A A A are also cast integral with or secured to the upper limb of the binder-frame. The binder an d discharging-arm shaft is j ourn aled in the offsets A A A.

The lower limb of the binder-frame forms a journal-bearing for the needle-arm shaft B, to the forward end of which is secured a crank-arm B, on a stud in which and on a stud ecceutrically secured to the gear-wheel O is pivoted a pitman 0, through which the necessaryreciprocating movement is imparted to the needle by the revolution of the gearwheel 0 to place the band around the center The packershaft A extends forwardly beyond the vertical binder-post and carries pinioned or otherwise rigidly secured thereto a clutch-collar a, provided with the clutch-teeth a.

The sprocket-wheel D is loosely mounted on the packer-shaft next to the clutch-collar a. The hub of the sprocket-wheel is provided on either side with a clutch-face d c l, and the inner side of the hub of the sprocketwheel is formed with a circumferential groove (1 into which takes a nose-piece K, rigidly fastened to the binder-frame, so as to hold the sprocket-wheel always in the same vertical plane. The sprocket wheel runs constantly, and is driven by a sprocket-chain running from some suitable constantly-running sprocket-wheel on the harvester.

Loosely mounted on the packershaft A is a pinion a formed with the clutch-teeth a to engage the clutch-teeth (Z of the sprocketwheel or driver D. The gear-wheel O, which is secured to the binder-shaft and through which shaft motion is communicated to the knotting devices and the discharge -arms, meshes with the pinion a and when the clutch-teeth of the latter are in engagement with the clutch-teeth d of sprocket D the gear-wheel O is caused to revolve. The packershaft A carries on its rear end a gear wheel or pinion I), which meshes with a gear-wheel b, secured to a shaft which carries the disks Z), to which are pivoted the packer-fingers I) Z), which, coming in contact with the grain delivered by the harvester, compact it against the tripping device. It is evident that when the clutch-collar a is in engagement with the clutch-teeth (Z 011 the sprocket-wheel D the shaft A will be driven, thereby imparting motion to the packers.

Securely pinned to the shaft A is a collar (0, between which and the clutch-pinion (t is interposed a spiral spring a. J ournaled in the offset A" is a lever F, which is bent at f and carries a friction-rollerf, which takes into a cam-groove f on the wheel C. The other end of the lever F carries a yoke f which fits over the shaft A and bears against the face of the collar a". The cam-groovef is depressed at f", and into the depression f the roller f rests when the packers are in operation.

G is the trip-shaft, suitably journaled in the binder-frame and carrying the trippingarm g, which overhangs the bindingaeceptacle, and against which the crop is forced to start the binding devices and stop the packers. The forward end of the tripping-shaft has secured thereto a downwardly-projecting arm II, which arm carries at its upper end the segmental piece 7!, provided with the adjusting-teeth h. A spiral spring 7L2 is coiled around the shaft, and one end abuts against the binder-frame and the other against one of the several adj usting-teeth h. The lower end of the arm l'I carries a pin or stud h on which is loosely mounted the lower end of the yoke ll which, extending upwardly, is provided with a semicircular opening M, which fits over the hub of the gear-wheel a and abuts against the collar to, turned or otherwise formed 011 the gear-wheel. The gearwheel 0 is provided on either side with lugs c c, and as the gear-wheel O revolves these lugs c 0 come, respectively, in contact with the portions 7r h of the yoke ll. A strong spiral spring 71' is interposed between the lower end of the yoke H andawasher pinned on the end of the stud 7L3.

The operation of myinvention is as follows: Supposing the parts to be in the position shown in Fig. 1, the collar on the end of the shaft A having its clutch-teeth in contact or engagement with the clutch-teeth on the hub of the sprocket-wheel D, and the clutchteeth 011 the pinion a out of engagement with the clutch teeth (Z, the packcrshaft A, through the clutch-collar a, fast thereto, will be revolved, and the packers will thereby be driven. As soon, however, as sufficient grain has been forced by the packers underneath the tripping-arm g to depress the arm II, thereby forcing the arm it of the yoke II from the lug c, the spring a will be free to act and will move the pinion a? forwardly, so that its clutch-teeth will engage with the clutch-teeth (Z, and the pinion will commence to revolve, thereby imparting motion to the gear-wheel 0. As soon as the gear-wheel 0 starts the cam f will raise the friction-roller f out of the depression f and the yoke f being thereby forced against the collar (0, fast to the shaft A, will slide the shaft forwardly, disengaging the clutch-collar a from the clutch-teeth d, and the packers will come to rest. The forward movement of the packerdriving shaft A is not sufficient to totally disengage the pinion I) from the gearl); but the teeth of the latter, and also of the pinion Z), are suificiently long to permit the sliding movement of the shaft A to disengage the clutch which operates the packer-driving shaft without disengaging Z) and b. It will be noticed from the abruptness of the cam-groove atf" that the initial movement of the gear-wheel C brings the packers to rest, and a clear space is afforded the needle-arm in its ascent to bring the band around the bundle. As the gear-wheel Ccontinues its revolution the kn ottyer and the discharge-arms will be operated to bind the bundle and eject it from the machine. As the gear-wheel O is nearing the completion of the revolution the ledge or lug 0 will come in contact with the portion and the lug c with the portion h. The lug c is wedge-shaped, as shown, and it tends to move the clutch-pinion a out of engagement with the clutch-teeth. Ll. Inasmuch, however, as the portion 7r bears upon the lug c, the wedge-shaped lug c, as the wheel 0 revolves, will force the lower end of the yoke II outwardly or forwardly, thereby compressing the spiral spring 7L, the yoke ll being pivoted sufficiently loosely upon the hub of the piir ion to permit this lateral movement of the lower'end of the yoke. As soon as the portion 7r has been relieved from the lug c the spring 7L" will be permitted to act suddenly, thereby overcoming the spring a, than which it is stronger, and the clutches a and (Z will be totally disengaged. The shaft A will be also moved rearwardly and the clutch-collar (L be brought into engagement with the sprocket-wheel clutch (Z, the roller f again falling into the depression f" and the packers again started and the binder stopped, ready for the accumulation of the succeeding sheaf and the succeeding operation of the tripping device.

It will be noticed that the lug 0 acts as a fulcrum for the yoke-lever II in compressing the spiral spring h. It will also be noticed that the compression of the spiral spring it throws the packer-shaft baelnvardly, so that the clutch-collar a is again brought into e11- gagement with the clutch-teeth (l and the frietion-roller f again caused to drop into the depression. The spiral spring which acts to throw the binder-driving clutch into engagement with the driver" also acts to slide the packer-driving clutch into engagement with driver. The two clutches are thus thrown into engagement yieldingly, so that the points IIO driving clutch and the collar fast on the shaft and the spring at. the lower end of the yoke are compressed. The expansion of the latter springwhen released serves to continue the separation of the spring-pressed binder-driving clutch from the driver, compressing its spring, which subsequently, partially expanding, acts against the collar fast on the shaft, sliding the latter to bring the packer-clutch into engagement with the driver, the binderdriving clutch being held against the action of the spring by the yoke and wedge-shaped lug on the binder-driving gear. The packerdriving shaft is kept from being moved longitudinally until the binder-driving clutchpinion is freed from the driver by means of the roller on the lever journaled in the offset of the binder-frame, which roller traverses the cam on the binder-driving gear. When, however, the binder clutch-pinion is freed from the driver, the roller registers with the depression of the cam on the gear-wheel; but until this time the separation of the clutchpinion from the driver compresses the spring between the pinion and the collar fast on the packer'driving shaft, which spring as the roller registers with the depression in the cam on the binder-driving gear is free to act to force the paoker-clutchinto engagement with the driver, as hereinbefore explained.

I am aware that I am not the first to use a continuously-revolving driver provided with clutching mechanism on either side in conjunction with clutches on either side of the driver, the one to operate the binder and the other the packers, together with mechanism for alternately shifting the clutches; but I believe that I am the first to use a driver provided on either side with clutching mechanism and mounted loosely on a driving-shaft in conjunction with a clutch fast on the same shaft and the clutch-pinion loose on the same shaft with mechanism to slide the shaft and clutch-pinion alternately. The advantages of this. arrangement are its simplicity and its economy of construction. It will be noticed that when the binder is in motion its driving-pinion is clutched to the driver, which, together with the pinion, revolves loosely on the driving-shaft, and the binder coming to rest, the clutch-collar fast on the drivingshaft being clutched to the driver, the latter revolves with the shaft. It will also be noticed that by sliding the driving-shaft of the packers longitudinally the looselyunounted driver is always kept in line with its corresponding sprocket-wheel from which it obtains its motion, and that the sprocket-chain which runs the driver is always kept in alignment. This arrangement also brings the various co-operative parts more closely together, making the machine more compact.

I claim 1. The combination, with a longitudinallysliding packer-driving shaft and a constantlyrevolving driver mounted loosely thereon and a cl utch-collar secured thereto, of a clutch on the driver, the gear-wheel on the bindershaft, and a cam-groove formed on the face thereof, a lever journaled in thebinder-frame and having a roller on one end taking into the cam-groove, and a yoke at the other end bearing against the packer driving shaft, whereby the initial movement of the gearwheel on the binder-shaft operates the lever to-slide the packer-driving shaft through the driver, so that the clutch-collar on thepackerdriving shaft will be disengaged from the clutch on the driver, substantially as and for the purpose specified.
